At the Bugzilla project meeting on 2015-03-25 the project lead and
assistant leads agreed on two major changes to Bugzilla's source-code
1. CVS support is officially dropped as of now. 4.0 is the last version
that was released on CVS, and it will be EOLed when 5.0 comes out (very
soon; rc3 was just released). In the event of a release on the 4.0
branch before it is EOLed, any Bugzilla installations that have not
migrated to bzr or git will have to apply patches to upgrade, which
will continue to be distributed as usual. Bugzilla site admins are
strongly encouraged to migrate to pulling from git.mozilla.org as
soon as possible.
2. Bazaar hosting has been officially switched from bzr.mozilla.org to
bzr.bugzilla.org. bzr.bugzilla.org is already active and syncing changes
from git.mozilla.org. bzr.mozilla.org is no longer syncing changes and
will soon be shut down. Any sites upgrading from bzr.mozilla.org *must*
do one of the following to apply any future upgrades, in order of
* Switch to upgrading from git.mozilla.org.
* Switch to pulling from bzr.bugzilla.org. See instructions at
* Apply the released patch.
bzr.bugzilla.org will continue to mirror changes from git.mozilla.org
for the 4.0, 4.2, and 4.4 branches as long as they are supported. Note
that, at the moment, master/trunk is being mirrored as well, but no
other branches, including and subsequent to 5.0, will be mirrored to
bzr.bugzilla.org, and trunk mirroring may cease at any time.
Note that bzr.bugzilla.org is waiting on a proper certificate; please
use plain http until this is resolved.
The Bugzilla team apologizes for any inconvenience. Please see our
support options if you have trouble migrating.
